I just bought a vafc to get rid of the blue box on my greddy kit...does anybody have some base #'s for the 310's and 5psi of boost? I'm not going to raise the boost for a while, so that's why I'm sticking with the 310's. Any help would be great!!!

 

richer richer richer...
Not many people use 310cc injectors and try to hack...

 

Couldn't you just take out less fuel?

I cant say for certain but I highly doubt that 310 cc injectors will provide enough fuel for 5psi of boost. The reason it works with 450cc injectors is because they provide more then enough fuel. The ecu will probably compensate for the difference in injector size (240 vs 310)...Im runing 310's and still need fmu to get enough fuel, I'm using a sfc to lean it out a little 5-15% with a 4:1 fmu. But i also have a strange ecu, it dumps fuel in the gallons for some reason???
Most people use a 8:1 fmu w/310cc injectors and everything runs fine, I run a 4:1 and my air/fuel ratio is still too rich (10.0 +) once boost hits....

 

The greddy kit comes with 310's...and it's running rich as hell when gets into boost. I didn't know if anybody has ever run the vafc with the 310's, just to get rid of the blue box...and upgrade in the future. I'm going to run 440's, but not right now.

 

****.....i have setting off a SAFC not VAFC....

i know the VAFC has narrow throttle setting unlike the SAFC....

if u want the SAFC ones let me know....

i have a dyno'd settings

It won't work. You will run really lean up top and even if you didn't you have to have atleast -35% in boost or you will throw a code because your ecu will see positive pressure.

 

yea i thought about doing this but found out its not as good as it sounds... keep the **** box until you can afford something better, its not too bad for 5psi, unlike everyone says
